At day 4 we’re nearly half way through the event. Hope you’re all chatting, asking and voting!

Today’s highlights in the Tin Zone:

• Creating impossible creatures…

Is there such thing as a snurtle turtle/snail?

• We learnt more about snails:

How do snails have babies? Are baby snails born with shells?

• And breaking metal with your bare hands…

If you put a sheet of metal in dry ice for long enough could you break it with your bare hands?
